Specification of Letters Patent.

No. 36?,OYG.

Serial No 5825-15.

Divided and this application filed September her in -\vhich chemical elements or com-' pounds in gaseous i.' r1n n1a react to form new compounds, and the igslcctrical means whereby the chamber may h ated to the desired degree of tcmperatine.

The electrically heated chamber in which the presentinvention is embodied is capabic of employment. among other uses in con nection with chemical apparatus such as that described and claimed in Letters Patent 1.009.428, granted to me Nov. 21, 1911, for apparatus for producing chloride of carbon, of which application the presentone is a division.

An embodiment of my invention in a action chamber, adapted to be electrically heated to cause gases to react on one another, and an apparatus in which such re action chamber may be employed, are illustrated in the accompanying drawings, fornn ing part of this application, and are de scribed in the following specification, apparatus for producing chlorids of carbon being here shown for illustration of one possible use of the invention, but not in any sense 'as a limitation of the use of the same to combinations of the particular "11868 from which chlorids of carbon are made.

In the drawings Figure 1 represents a reaction chamber, in which. my invention embodied, in yer ical section. Fig. 2 is a cross-section on line 22 of Fig. 1. Figs. 3 and 4 represent respectively 51 plan and elevation of an apparatus in connection with which the electrically heated reaction chamber forming the subject of the presentinvention is adapted to be used.

The same reference characters indicate the same parts in all the figures.

The reaction chamber is designated by the numeral 21 and in its present embodiment has branches 22 23 leading, from its lower portion to stacks 22, 23, respectively. through which the gases which are intended to react upon one another are conducted to the chan'iber.

A convenient arrangement and constructi on of the reaction chamber is to have twobranches extending oppositely and to pro vide an eq irl number of stacks between which the chamber 2 s are conveniently on mined partly in a pan or other receptacle 60 adapted to hold water, and maintained in any sui: support, the chamber bleframe or being supported so that a regulation of the heat of the chamber may be effected by means of the Water in the pan. A convenient means for supporting the chamber and stacks independently of the pan con- Sluhfi 1 and 320a which the upper part of the reaction chamber rests, bars 3 and 65 hung from said slats by bolts 64 and it slats 6'11 68. a bar 63 hung from i by bolts 70, a

bar 71 hung from (in? by bolts 79.. and inclined slats ing: on the bars 63, 69, and 55, 71 retel The slats Gl. G2; 67 and 68 are adapted to be supported independent of the pan by 2 .ins not shown.

Gas admitted to the stack through the inlets S6, 87 and 88 are permitted to flow through the branch 22* into the. lower part ofthe chamber Where they are heatedby the electrical means hereinafter described, and after forming new compounds are conducted away from the upper partof the stack through a pipe to a condenser or other receptacle 51. Likewise the sub? stances to be combined entering the stack 23 through the inlet ports 80, 81 and 82 flow throu 'h the branch 23 into the reaction chamber and are combined in like manner and conducted away through. the outlet 50.

The cross sectional area of the lower part of each stack 22, -23, is subdivided for a short distance to increase the cooling surface by 'nieans of a chamber 76. The subdivided part oi. each stack is surrounded by water jacket 7'? of any suitable material. Two diaphragins 83 are arranged on either side of the port 852 and extend down a'substantial distance into the stack, permitting the natural gas toenter the stack, but keeping it separate from the substances entering ports 80, 8]. The stack 22 is pro- Vltliti with diaphragms S9. 90 corresponding with the diaphragms 83, 84.

The electrically heated portion of the react-ion chamber is constri zctcd of a. material which is adapted to w stand this no ion of heat and the chemical a ii: of tine reacting substances, and which is also a non-coo ductor of electricity. A material whim l find convenient for this purpose is soap stone. The main partot the chamber is accordingly preferably made from a block oi this material 91, by cnttii a hole in interior so as to have s all in me piece Without joints .mecior oi: the chamber and of the branches 23* is filled with a suitable pol rizeiil material such as coke, in order to zit the training and reaction of the 'ilbs'il-ilitiili w ithout; eniplosion.
